[Infra] Initial Migration off GCP Runners (#18381)

This commit is part of this larger issue that is tracking our migration
off the GCP runners, storage buckets, etc:
https://github.com/iree-org/iree/issues/18238.
In this initial port, we move over one high traffic job
(`linux_x86_64_release_packages`) and a few nightlies
(`linux_x64_clang_tsan`, `linux_x64_clang_debug`) to monitor and make
sure the cluster is working as intended.

Time Comparisons:

Job | Cache? | Runner cluster | Time | Logs
-- | -- | -- | -- | --
linux_x86_64_release_packages | GitHub Cache | AKS Cluster | 9 minutes |
[logs](https://github.com/iree-org/iree/actions/runs/10797464301/job/29948809708)
linux_x64_clang_tsan | GCP Cache | AKS cluster | 10 minutes |
[logs](https://github.com/iree-org/iree/actions/runs/10797464292/job/29948816896)
linux_x64_clang_debug | GCP Cache | AKS cluster | 11 minutes |
[logs](https://github.com/iree-org/iree/actions/runs/10797464308/job/29948805561)
linux_x64_clang_tsan | No Cache | AKS cluster | 17 minutes |
[logs](https://github.com/iree-org/iree/actions/runs/10798471545/job/29952051686)
linux_x64_clang_debug | No Cache | AKS cluster | 13 minutes |
[logs](https://github.com/iree-org/iree/actions/runs/10798475582/job/29952064138)

[logs](https://github.com/iree-org/iree/actions/runs/10789692182/job/29923234380)

The GCP cache timings for the AKS cluster are not a great representation
of what we will be seeing going forward because the AKS cluster does not
have the setup/authentication to write to the GCP cache. We have changes
coming in
https://github.com/iree-org/iree/tree/shared/runner-cluster-migration
that will spin up an Azure cache using sccache to help with the No Cache
timings. Right now the cluster is using 96 core machines, which we can
probably tone down when the caching work lands.
